Iivalve zebhola ze-Cryogenic ezineebhonethi ezandisiweyo ezifanelekileyo zokusebenza kumaqondo okushisa aphantsi -196 ° C zenzelwe ngokukodwa ukujongana neemeko ezigqithisileyo zezicelo ze-cryogenic.Ezi valves zisetyenziswa ngokuqhelekileyo kumashishini afana ne-LNG (i-liquefied natural gas) processing, i-gas ye-industrial production, kunye nezinye izicelo zokuphatha i-cryogenic fluid.Iimpawu eziphambili zeevalvu zebhola ze-cryogenic ezinebhonethi ezandisiweyo ze -196 ° C zibandakanya: Izinto eziphantsi kobushushu: iivalve ngokuqhelekileyo zakhiwe ngezinto ezikhethekileyo ezifana nentsimbi, intsimbi ye-carbon, okanye ezinye i-alloys ezine-low-temperature properties ukuze kuqinisekiswe ukusebenza kunye nokuthembeka kwiindawo ze-cryogenic.Uyilo lwebhonethi eyandisiweyo: Ibhonethi eyandisiweyo inika ukugquma okongeziweyo kunye nokukhusela i-valve stem kunye nokupakisha. ukugcina ukusebenza okufanelekileyo kumaqondo obushushu aphantsi kakhulu.Ukutywinwa kunye nokuPakisha: Amacandelo okutywinwa kwevalve kunye nokupakishwa kuyilelwe ngokukodwa ukuba ahlale esebenza kwaye ebhetyebhetye kumaqondo obushushu e-cryogenic, evumela ukuvalwa okuqinileyo kunye nokuthintela ukuvuza. qinisekisa ukusebenza kunye nokuthotyelwa kwemigangatho yoshishino lwenkonzo ye-cryogenic.Ukhuseleko lokuSebenza: Iivalve zebhola ze-Cryogenic ezineebhonethi ezandisiweyo zibalulekile ekugcineni ulawulo olukhuselekileyo noluthembekileyo lokuhamba kwe-cryogenic fluid, igalelo ekukhuseleni okusebenzayo kwiinkqubo ze-cryogenic.Xa ukhetha iivalve zebhola ze-cryogenic ze -196 ° C izicelo, kubalulekile ukuqwalasela imiba enjengokuhambelana kwezinto, uxinzelelo kunye neqondo lobushushu, kunye nokuthotyelwa kwemigangatho yoshishino efanelekileyo kunye nemimiselo.
I-API 6D ivalve yebhola yetrunnion yimveliso yevalvu yebhola ehlangabezana neemfuno zomgangatho we-American Petroleum Institute API 6D.Lo mgangatho uchaza ukuyila, izinto, ukuvelisa, ukuhlolwa, ukufakwa kunye nokugcinwa kweemfuno ze-API 6D iivalvu zebhola ze-trunnion ukuqinisekisa umgangatho kunye nokuthembeka kweevalvu zebhola, kwaye ifanelekile kwiinkalo ezahlukeneyo zoshishino ezifana ne-oyile kunye negesi.Iimpawu ze-API 6D ivalve yebhola yetrunnion ziquka:
I-1.Ibhola eligcweleyo lisetyenziselwa ukunciphisa uxinzelelo lwe-valve kunye nokuphucula umthamo wokuhamba.
I-2.I-valve ithatha isakhiwo sokutywina ngeendlela ezimbini kunye nokusebenza kakuhle kokutywinwa.
I-3.I-valve ilula ukusebenza kwaye igudileyo, kwaye isibambo siphawulwe ukuchongwa lula ngumqhubi.
I-4.Isihlalo sevalve kunye nendandatho yokutywina zenziwe ngeqondo lokushisa eliphezulu, i-high-pressure kunye ne-corrosion-resistant materials, ezifanelekileyo kwimidiya eyahlukeneyo yamanzi.
5. Amalungu evalve yebhola ahlukana kakuhle, kulula ukuyifaka kunye nokugcina.I-API 6D iivalvu zebhola ze-trunnion zifanelekile kwizihlandlo kwintsimi yoshishino efuna ukulawula ukuhamba kwamanzi, ukunqumla ulwelo, kunye nokugcina ukuzinza koxinzelelo, njengeenkqubo zemibhobho yamanzi kwi-petroleum, imichiza, igesi yendalo, unyango lwamanzi kunye nezinye iindawo.
